如何根据特定条件过滤 dataweave 中的响应？

Question

假设我从 API 呼叫中收到以下响应。

accounts: [

accountName: "A",
amount: 10$

account Name "B closed",
amount: 20$

]

我想过滤所有在帐户名称中包含 closed 关键字的帐户响应。谁能告诉我如何根据此过滤所有包含已关闭的响应并只给我帐户 A.

我正在为我的 mulesoft 代码使用 dw 1.0。如果您还有其他问题，请告诉我。

假设您的输入是：

{
  "accounts": [
    {
      "accountName": "A",
      "amount": "10$"
    },
    {
      "accountName": "B closed",
      "amount": "20$"
    }
  ]
}

然后你可以这样过滤：

%dw 1.0
%output application/json
---
payload.accounts filter ((account) -> not (account.accountName contains "closed"))

这将导致：

[
  {
    "accountName": "A",
    "amount": "10$"
  }
]
